Log

This section contains the APIs related to logging.

Listen to console.log events

Listen to the console.log events and register callbacks to process the event.

        try (LogInspector logInspector = new LogInspector(driver)) {
            CompletableFuture<ConsoleLogEntry> future = new CompletableFuture<>();
            logInspector.onConsoleLog(future::complete);

            driver.get("https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html");
            driver.findElement(By.id("consoleLog")).click();

            ConsoleLogEntry logEntry = future.get(5, TimeUnit.SECONDS);

            Assertions.assertEquals("Hello, world!", logEntry.getText());
            Assertions.assertNull(logEntry.getRealm());
            Assertions.assertEquals(1, logEntry.getArgs().size());
            Assertions.assertEquals("console", logEntry.getType());
            Assertions.assertEquals("log", logEntry.getMethod());
            Assertions.assertNull(logEntry.getStackTrace());
        }

Listen to JS Exceptions

Listen to the JS Exceptions and register callbacks to process the exception details.

        try (LogInspector logInspector = new LogInspector(driver)) {
            CompletableFuture<JavascriptLogEntry> future = new CompletableFuture<>();
            logInspector.onJavaScriptException(future::complete);

            driver.get("https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html");
            driver.findElement(By.id("jsException")).click();

            JavascriptLogEntry logEntry = future.get(5, TimeUnit.SECONDS);

            Assertions.assertEquals("Error: Not working", logEntry.getText());
            Assertions.assertEquals("javascript", logEntry.getType());
        }

Listen to JS Logs

Listen to all JS logs at all levels and register callbacks to process the log.

        try (LogInspector logInspector = new LogInspector(driver)) {
            CompletableFuture<JavascriptLogEntry> future = new CompletableFuture<>();
            logInspector.onJavaScriptLog(future::complete);

            driver.get("https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html");
            driver.findElement(By.id("jsException")).click();

            JavascriptLogEntry logEntry = future.get(5, TimeUnit.SECONDS);

            Assertions.assertEquals("Error: Not working", logEntry.getText());
            Assertions.assertEquals("javascript", logEntry.getType());
            Assertions.assertEquals(LogLevel.ERROR, logEntry.getLevel());
        }
